Hi guys, newbie here, and I recently purchased my first GTO, its the 1991 NA model, but we have to start from somewhere.
Im having two issues, which im not sure if they are related:
firstly the car is sluggish on acceleration at low revs/ low speeds. At high speed on the motorway it seems to be ok. Im hoping its just fresh set of spark plugs, and maybe HT leads should sort that out
Second issue is that i am getting the overheating Catalytic converter light come on the dash. But I know its not over heating as its on constantly. As in first thing in the morning when the car is stone cold
but the light stays on.
Any one has any ideas? or has had this issue before? Ive read online that there is chance of a blocked Cat.
any help would be greatly appreciated.
